A panel-show stalwart, Bea has crafted a successful career on the comedy circuit, becoming a familiar favourite on shows such as 8 Out of 10 Cats does Countdown, Taskmaster and Live at the Apollo.

With This Way Up, Bea finds her signature voice in the world of TV’s scripted comedy. A triple threat as the writer, executive producer and star of the series, Bea has taken less of a cautious first step, and more a running leap into the creative medium.

The series, adapted from Graham’s play of the same name, explores the story of the ‘coughing major’, which saw Charles (Matthew Macfadyen), Diana Ingram (Sian Clifford) and Tecwen Whittock (Michael Jibson) cheat their way to a million pounds on the quiz show Who Wants to Be a Millionaire?

The “audacious heist” took place in 2001, when Major Ingram was a contestant on the show and with the help of his wife Diana and accomplice Whittock, navigated the notoriously difficult quiz to win the top price.

James Graham was an undergraduate at Hull University when he became fascinated by daily press reports of the trial of a respectable home counties couple accused of cheating their way to the top prize in ITV’s Who Wants To Be a Millionaire? At the time, Millionaire was one of the biggest shows on TV, achieving audiences of more than 8 million; at its peak, an incredible 19 million tuned into the programme.
